Coupled Hover Events

N/A — JavaScript-only linked subplot hover

The JS example synchronises hover across subplots using Plotly.Fx.hover called inside a plotly_hover callback — requires direct access to multiple graph divs.

In Livebook, layout.hovermode: "x unified" achieves a similar visual effect natively (all traces at the same x show in one tooltip) without custom JS.
